My STi can't even keep up with the power demands in normal commuting... I have to charge the battery every 2 weeks or so :(

That means there is something wrong with it.

That's a bit underwhelming. I assume this is one of those cars that is capable of exceeding the estimated mpg?

My 13 yr old Corolla gets 33 combined, for crying out loud

Before you go thinking that means the Fiesta is some sort of hybrid or electric car, think again. Instead, it's an intelligent system of control for charging the car's battery. Previously, the alternator was permanently hooked up to the engine when running. Here the Fiesta only engages the alternator when you're coasting, slowing down, or idling, which reduces wear and tear on the engine and other components in the system. Hopefully that should mean your battery is always charged for powering all the latest car tech, while lasting longer and needing less servicing."

Sounds very similar to the "iE-Loop" system on the new Mazda 6s. The Mazda system uses the disengaging alternator paired with a giant capacitor system that supplies energy in some sort of bleed back to the electronics. Early models like mine don't have it, but that and the engine shutdown at traffic lights is supposed to be good for +10% mpg.
